PDF Rod Seal – A high-performance double-acting rod seal engineered for hydraulic cylinders requiring reliable bidirectional sealing with integrated contamination resistance. This innovative seal design features a primary sealing lip that delivers positive sealing in both stroke directions under pressure, combined with a secondary wiper lip that acts as a light excluder — removing surface contaminants and retaining lubrication film during rod retraction.
The optimized lip geometry ensures low friction and minimal heat generation across the entire operating range, significantly extending seal service life. The compact cross-section fits standard rod groove profiles, making it ideal for space-constrained hydraulic applications where both sealing efficiency and contamination protection are essential.
Manufactured from high-performance polyurethane, the PDF seal offers excellent abrasion resistance, extrusion resistance, and compatibility with a wide range of hydraulic fluids. The integrated wiper function reduces the need for separate excluder components, simplifying assembly and reducing overall system cost.
Whether used in mobile equipment, industrial machinery, or agricultural hydraulic cylinders, this contamination-resistant rod seal delivers consistent, leak-free performance in moderately contaminated environments. Available in standard sizes to fit most cylinder configurations. Backed by rigorous quality control and OEM-grade manufacturing standards.
